Fisher Paykel DD6031 Double Dish Drawer - does it have diagnostic mode?

This is an integrated appliance with no display, just the power, start/pause and lock buttons (plus the usual wash mode buttons inside the drawer).

I have seen that other models with a display have a diagnostic mode which enables you to test the lid actuator to see if the lid is shutting properly.

I am pretty convinced that the top drawer lid is not shutting properly because the pan in the base is swamped with water (didn't take a lot of reasoning!!). The bottom drawer functions perfectly.

Is there a way of entering diagnostic mode on this model DD6031 and what is the sequence?

thanks in anticipation
